I love this stuff. The bond is extremely strong, it's easy to use, and the cap is extremely effective. I've had this tube for months and it shows no signs of drying or leaking. When mixed it has a thick almost puddy like consistency. This makes it easy to shape and fill irregular spaces, and it doesn't drip or deform while curing. I've used this in several small car repairs, and cracked plastic cases for tools. Every repair is holding up just fine. Remember to clean the area and rub it with an alcohol swab before using this. It still follows the same rules as glue and if you try to use it on a dirty section it won't stick. I've found its performance to be on par with regular JB Weld. Anyone who has ever used JB Weld knows how high of a compliment that is. I highly recommend this. It is easy to use and, if done correctly, extremely strong.

I didn't like how it came oozing out in an uneven pace while removing the cap. But, mixing the equal parts turned out to be highly successful in binding and filling broken pieces of a motorcycle fairing. I will know more about it's propensity for binding and maintaining plastic pieces once I begin bolting the fairings back on the MC. So far so good. A few miles under normal use should prove out one way or the other.

Used to glue a black plastic piece on my utv. Works great. Holds together two pieces. Just not seamless. You can tell it’s been patched.

I bought this stuff to reattach my door panel by the window. I have a ford explorer interceptor utility and it was a recall on them and I missed the recall so I fixed it my self and it works great bonds around 10mins and it still is hold after a month.
